ABSTRACT:
A generally circular pipe joint clamp able to compress a flexible packer around a joint between substantially aligned pipes. The clamp comprises a plurality of plates forming a flexible shield. Each plate overlaps one neighboring plate and underlies the other neighboring plate. There is a joint in between each pair of neighboring plates except the plates at each end of the flexible shield to allow the plates to pivot relative to each other. Clamps allow a compressing force to be applied to the flexible shield.
